Just use docker image, but don't use docker run.

I'm not using kubernetes, I just want to run two containers from a docker-compose stack

wondering if it might be a udp thing. if you go tcp does it work?

Yeah, a DNS query over TCP on port 5300 from the host works

may be a limitation of the forwarding into the VM because its connectionless

ah yes, couldn't find that earlier

won’t be as performant, but most named will support tcp. it is a bit of a change for the consumers though so it may not be a workable option

it does, and luckily I am only putting a few thousand queries per second through it - I'll probably have to switch to docker engine on a separate box or back to docker desktop, I guess!
